As previously reported, a letter that Madonna wrote to someone known as “J,” thought to be actor John Enos, in the early ’90s is being auctioned off. In the letter, Madonna writes that she finds it frustrating when people say that Whitney Houston and Sharon Stone have better careers than she has.

She then writes, “Not because I want to be these women — because I’d rather die — but they’re so horribly mediocre and they’re always being held up as paragons of virtue or some sort of measuring stick to humiliate me.”

On Facebook, Stone writes, “Dear Madonna, First, I think it’s absurd that anyone is publishing your private letters. Therefore; I publish publicly. Know that I am your friend. I have wished to be a rock star in some private moments…have felt as mediocre as you described.”

She adds, “We know, as only those who have survived so long that owning our own mediocrity is the only way to own our own strengths; to become all that we both have become. I love and adore you; won’t be pitted against you by any invasion of our personal journeys.”
